Abstract
The invention relates to the technical petroleum mounting and demounting machinery, in particular to an ultra-short distance clamping mechanism for a makeup and breakout unit. The ultra-short distance clamping mechanism comprises a support and a hydraulic cylinder. A connecting lug is fixed on the right of the support. The hydraulic cylinder is fixed at the center of the support. The bottom of the hydraulic cylinder is fixedly connected with one end of a connector through a screw. The other end of the connector is hinged to one end of a first connecting rod through a pin. The other end of the first connecting rod is hinged to a jaw plate assembly through a pin. A plurality of adjusting holes are formed in the middle of the first connecting rod. The adjusting holes are hinged to one end of a second connecting rod through a pin. The other end of the second connecting rod is hinged to the connecting lug through a pin. When the ultra-short distance clamping mechanism is used, small clamping distance between a main clamp and a back clamp is achieved, the clamping distance can reach 5mm, controllability of clamping positions and lengths of some parts is achieved, manpower cost is saved, and the outer surface of some tools is protected from being destroyed. In addition, the ultra-short distance clamping mechanism is simple in structure, reasonable in configuration, low in manufacturing cost, and the like.
Description
Technical field
The present invention relates to oil dismounting field of mechanical technique, particularly a kind of thread screw on and-off machine very-short-reach clamp mechanism.
Background technology
Thread screw on and-off machine is a kind of threaded connector loading mechanization, is mainly applicable to oil field well pump, downhole tool, and oil pick-up tube oil pipe, turning of other threaded connectors such as pipe box joined and dismounting.
Existing thread screw on and-off machine structure is mainly comprised of main pincers and back-up tong, back-up tong is clamped body and is not rotated, main clamp body rotation, between body and body, be threaded, owing to being subject to the restrictions such as main pincers, back-up tong side plate thickness, main, that back-up tong clamps spacing is large, generally all reach more than 150 millimeters, due to drill and petroleum extraction tools (as: packer, sand preventing tool etc.) structure relative compact, component are irregular, during dismounting, need main, that back-up tong clamps spacing is less, indivedual component can clamped position and length limited, existing thread screw on and-off machine can't meet the demands in the market.
Therefore,, based on the problems referred to above, be necessary to provide a kind of thread screw on and-off machine very-short-reach clamp mechanism.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of simple in structure, thread screw on and-off machine reasonable in design, easy to use very-short-reach clamp mechanism.
For achieving the above object, the technical solution used in the present invention is:
A kind of thread screw on and-off machine very-short-reach clamp mechanism of the present invention, include support, hydraulic cylinder, connector, connecting rod one, connecting rod two and Hubei Province plate assembly, described support right side is fixedly installed engaging lug, described support centre is fixedly installed hydraulic cylinder, described hydraulic cylinder bottom is fixedly connected by screw and connector one end, and the connector other end is hinged by one end of bearing pin and connecting rod one; The other end of connecting rod one is hinged by bearing pin and Hubei Province plate assembly, and connecting rod one middle part is provided with several adjustment holes, and described adjustment hole is hinged by bearing pin and connecting rod two one end, and connecting rod two other ends are hinged by bearing pin and engaging lug.
As a kind of optimal way of the present invention, the quantity of described adjustment hole is three.
As a kind of optimal way of the present invention, the two ends of described bearing pin are all arranged with circlip for shaft.
As a kind of optimal way of the present invention, described screw is also nested with spring washer, and spring washer is arranged between hydraulic cylinder bottom and connector.
Adopt after said structure, beneficial effect of the present invention is: a kind of thread screw on and-off machine very-short-reach clamp mechanism of the present invention, include support, hydraulic cylinder, connector, connecting rod one, connecting rod two and Hubei Province plate assembly, described support right side is fixedly installed engaging lug, described support centre is fixedly installed hydraulic cylinder, described hydraulic cylinder bottom is fixedly connected by screw and connector one end, and the connector other end is hinged by one end of bearing pin and connecting rod one; The other end of connecting rod one is hinged by bearing pin and Hubei Province plate assembly, and connecting rod one middle part is provided with several adjustment holes, and described adjustment hole is hinged by bearing pin and connecting rod two one end, and connecting rod two other ends are hinged by bearing pin and engaging lug.Using when of the present invention, master while having solved dismounting, that back-up tong clamps spacing is little, and this spacing can be contracted to 5 millimeters; Having solved indivedual component can clamped position and the problem of the controllability of length, has saved cost of labor, has protected some tool exterior surface not to be damaged.The advantages such as the present invention has simple in structure, arranges rationally, and cost of manufacture is low.
